Overview

Randomized trial shows enhanced V2X communication security in vehicle networks, suggesting better protection against modeling attacks.

Key Points

  • This study aims to develop a secure and efficient authentication protocol for Vehicle-to-Everything communication.
  • Proposed a decentralized, dynamic authentication protocol for Vehicular Ad Hoc Networks.
  • Integrated Elliptic Curve Cryptography with Self-Adaption Deviation Locking PUFs to create a dynamic obfuscation mechanism.
  • Formal security verification under the Real-or-Random model using the AVISPA tool.
  • Reduced prediction success rate of attacks by approximately 35% compared to base PUFs.
  • Achieved low computational overhead of 6.77 ms per entity and communication cost of 192 bytes.
  • Provided superior robustness against advanced modeling attacks compared to existing methods.
